Abstract

The invention relates to a four corner pressure regulating device of a lower hydraulic cushion on a hydraulic machine, belonging to the technical field of the hydraulic machine. The four corner pressure regulating device of the lower hydraulic cushion on the hydraulic machine comprises a hydraulic pipeline and an electromagnetic valve and is characterized in that the four corners of the lower hydraulic cushion are provided with four plunger cylinders and each plunger cylinder is provided with an independent hydraulic control mechanism; and the hydraulic control mechanism independently controls the piston cylinder of the lower hydraulic cushion to stretch or jack up and return. The four corner pressure regulating device has the advantages of simple structure, convenient control, stability and reliability, comprehensive functions, excellent performance, low operational cost, easy implementation of the compression molding of complex work pieces and the like, and can be widely applied to hydraulic machine industries.

Description

technical field [0001] The invention belongs to the technical field of hydraulic presses, in particular to a four-corner pressure regulating device for a hydraulic cushion under a hydraulic press. Background technique [0002] At present, with the continuous development of science and technology, people's requirements for hydraulic presses are also constantly increasing. It is hoped that general stamping hydraulic presses can also realize functions such as stretching, bending, and forming of complex and irregular workpieces. Function, how to better adjust the pressure of the hydraulic cushion has become the main problem. The existing technology cannot adjust the pressure of the four corners according to the requirements, which makes it difficult to adjust the pressure of the four corners during stretching, and the scrap rate is high, which cannot meet the production needs, especially the hydraulic problems of special workpieces are more prominent. Contents of the invention...
